The internal conversion architecture is based on a R-2R resister ladder network, internal circuit is well matched and a 16 bit dynamic range is achieved even in low supply voltage. PT8211L also enhanced the performance of timing responsibility in digital serial bus, in a company with the fast switching R-2R network that make 8X oversampling audio signal is also supported. PT8211L can be supported wide range of sample frequency, it is compatible with TDA1311 by functionally. It’s digital input timing format is Least Significant Bit Justified (LSBJ), or so called Japanese input format. Digital code format is two’s complement and MSB first. PT8211L is available in 8-pin SOP or DIP package. PT8211L is designed for low voltage purpose, supply voltage can be down to 2V. FEATURES • • • • • • • • • CMOS technology Low supply voltage available (VDD=1.6V) Support 3.3V bus input level or lower Low power consumption Two audio channel output in the same chip 16 bit dynamic range Low total harmonic distortion No phase shift between both output channel Available in 8 pins, SOP or DIP APPLICATIONS • • • • Digital audio equipment CD ROM/VCD Multimedia sound card MPEG decoder card PT8211L V1.1 -1- March, 2006 Tel: 886-2-66296288 Fax: 886-2-29174598 URL: http://www.princeton.com.tw 16 Bit Digital to Analog Converter PT8211L PIN CONFIGURATION PT8211L V1.1 BCK 1 8 RCH WS 2 7 NC DIN 3 6 LCH GND 4 5 VDD PT82 11L -2- March, 2006 Tel: 886-2-66296288 Fax: 886-2-29174598 URL: http://www.princeton.com.tw 16 Bit Digital to Analog Converter PT8211L APPLICATION CIRCUIT AND NOTE For further suppress residual noise, we suggestion place an additional low pass filter after the analog output of PT8211L. Please refer to circuit shown on below, this is a simple second-order analog post filter. If low noise output is very important for your circuit design we suggestion uses regulated power supply. 1000pF 7.5K BCK RCH WS NC DIN LCH GND VDD PT8211L VDD 1000pF 7.5K 10 PT8211L V1.1 47 µ F 7.5K 7.5K Right Channel Audio Output op 470pF op Left Channel Audio Output 470pF 100nF -3- March, 2006 Tel: 886-2-66296288 Fax: 886-2-29174598 URL: http://www.princeton.com.tw 16 Bit Digital to Analog Converter PT8211L ORDER INFORMATION Valid Part Number PT8211L-S PT8211L PT8211L-S (L) PT8211L (L) Package Type 8 Pins, SOP, 150mil 8 Pins, DIP, 300mil 8 Pins, SOP, 150mil 8 Pins, DIP, 300mil Top Code PT8211L-S PT8211L PT8211L-S PT8211L Notes: 1.
